Hi Bernie, In answer to your question concerning Dr. Nordewin Diest-Koerber. I was unable to find him listed in Walther-Peer Fellgiebel's book, but he is listed in von Seeman's. He is also listed as a member of the OdR and his wartime rank as a Hauptmann d.R. and his award date as 1.5.45. If memory serves me right, there were some late war awards that were questioned by the OdR. The autographed photograph he sent to me does not show him wearing the Knights Cross. I hope that this is of some help. Regards, Dick
